The bead you choose mattersManufacturingOur tightly controlled manufacturing processes produce magnetic beads of uniform shape and size, with highly defined and consistent product characteristics. By reducing particle variability, more reliable and reproducible results can be achieved.
ReproducibilityThe level of reproducibility within and between batches of Dynabeads magnetic beads is unique. The same surface area is offered for each experiment, helping to ensure the best efficacy and reproducibility for your analysis. Inconsistent bead surfaces and sizes can trap unwanted molecules and compromise the quality and reproducibility of your results. Compare the uniform shape and size of Dynabeads products with magnetic particles from other suppliers (Figure 1).
Quality assuranceWe audit our suppliers and are routinely audited by our customers, as well as by the FDA and the Norwegian Notified Body (Det Norske Veritas Certification AS). Our quality system complies with ISO 9001:2015 (quality management systems) and ISO 13485:2016 (quality management systems for medical devices and regulatory purposes). The quality system is based on customer requirements and describes quality assurance in design, development, production, and servicing. It follows the requirements included in Quality System Regulations for Medical Devices (21 CFR part 820, US cGMP), when necessary.

It began in spaceNotable events in the history of Dynabeads magnetic beads
Following NASA’s success making
spherical polystyrene beads of exactly
the same size in the weightless conditions of space, Norwegian
professor John Ugelstad replicated the achievement here on
Earth. Another amazing achievement followed
when the uniform beads were made
magnetizable.
The superparamagnetic bead technology was licensed to Dyno Industrier.
Dynal AS started offering commercially
available superparamagnetic beads. The use of
Dynabeads magnetic beads for rapid one-
step isolation of functional CD8⁺ T cells
was reported [1].
The stimulation of T cells by CD3/CD28 antibodies conjugated
to Dynabeads magnetic beads was
published [2]. This research has led to exciting advances
in the field of cancer immunotherapy.
Kymriah™ T cell suspension, the first
commercially available T cell therapy, was
approved by the FDA for treatment of pediatric acute lymphoblastic
leukemia. Specifically developed Gibco™ CTS™
Dynabeads™ CD3/CD28 were first used for isolation, activation, and
expansion of T cells.

How Dynabeads magnetic beads workThe Dynabeads magnetic separation protocol generally consists of three simple steps. No centrifugation steps or columns are required for sample processing, and the protocol can be automated on Thermo Scientific™ KingFisher™ instruments.
Dynabeads Target proteinNonspecific protein
Antibody
Versatility of the Dynabeads magnetic beadsThere are two main considerations for Dynabeads products—bead size and coating. Many optimized Dynabeads magnetic beads are ready for immediate
use in a variety of applications; alternatively, you can easily prepare magnetic beads with your own antibody, oligonucleotide, or other ligand of choice.
Size: Dynabeads magnetic beads come in 4.5, 2.8, or 1.0 µm sizes for different applications. Typically, larger beads are used with intact cells for isolation and expansion. Smaller beads are used with molecules including proteins and nucleic acids.
Specificity: To capture specific cells or molecules, Dynabeads products can be purchased already conjugated to molecules like antibodies or protein G. The beads can also be included as part of a kit.
Flexibility: Streptavidin-coated or surface-activated beads can be used to customize the beads with your molecule of interest.
1. Bind: Dynabeads magnetic beads bind to the desired target (e.g., cells, microorganisms, nucleic acids, peptides, proteins, protein complexes, etc.). In the example shown, an antibody is attached to the surface of the magnetic bead.
2. Wash: The beads respond to a magnetic field, allowing bound material to be rapidly and efficiently collected on the magnet and separated from the rest of the sample. Unbound material remains in the supernatant and is simply removed by aspiration.
3. Elute: The bead-bound target is released from the surface of the beads in a suitable volume for use in downstream applications. Alternatively, the bead-bound target can be used directly while still attached to the beads.

Cell isolation
Isolate cells from mouse, human, or other species using a variety of positive or negative isolation or depletion kits. Gentle, tube-based magnetic separation isolates high yields of pure, viable, and functional cells. This technique also preserves the native characteristics of isolated cells, by avoiding passage of cells through a dense column.
With Dynabeads products, cell isolation is fast and flexible with no special instrumentation required, other than a magnet. Magnetic bead products have a long shelf life (minimum of 18 months) and can be used with tubes or to process multiple samples in 6-, 24-, 48-, or 96-well plates.

Dynabeads magnetic beads offer a fast, easy, and efficient method of pulling down proteins and other molecules of interest. This is why they are the most-cited magnetic beads in the literature for immunoprecipitation assays. The beads are ideal for the small-scale isolation of proteins or nucleic acids in applications such as immunoprecipitation (IP), co-immunoprecipitation (co-IP), chromatin IP (ChIP) and RNA IP (RIP).
Dynabeads magnetic beads help ensure the best balance of high yield and reproducibility with low nonspecific binding. Magnetic beads also enable higher-throughput applications, for which samples can be processed in 24- or 96-well plates manually, or on KingFisher instruments.
Key benefits• Low background—little to no nonspecific binding and
no preclearing required for high yields of pure proteins
• Highly sensitive—most-cited method for sensitive applications such as ChIP and IP
• Fast and easy—<40 min protocol with no centrifugation or preclearing steps
• Antibody savings—all binding occurs on the smooth outer surface of the beads, which conserves precious antibodies and supports a cost-efficient solution per sample
• Flexible—products for IP, co-IP, pull-down, and ChIP assays; ideal for manual and automated protocols

Co-immunoprecipitation (co-IP) is a popular method for the isolation of a target protein and its binding partners for analysis. Dynabeads kits offer quick and easy co-IP of intact, functional protein complexes so you only isolate the proteins of interest. Dynabeads magnetic separation is more effective than techniques using Sepharose™ beads and spin columns, which can dissociate fragile and large
protein complexes. The co-IP kit was developed to mimic intracellular conditions while providing customized stringency for different protein complexes in a cell solution. It offers the opportunity to optimize and fine-tune weak and transient interactions between short amino acid sequences in different proteins.

The chromatin immunoprecipitation (ChIP) assay is a powerful method for analyzing epigenetic modifications and genomic DNA sequences bound to specific regulatory proteins. ChIP experiments require a variety of steps, including crosslinking with formaldehyde, cell lysis (protein–DNA extraction), chromatin shearing, antibody-based immunoprecipitation, DNA sample clean-up, and PCR.
RNA immunoprecipitation (RIP) uses an approach similar to ChIP, except that RNA-binding proteins are immunoprecipitated instead of DNA-binding proteins. Immunoprecipitated RNAs can then be identified by RT-PCR and cDNA sequencing.
Because Dynabeads magnetic beads–based separation is gentle and sensitive, it’s ideal for capturing DNA and protein complexes. In fact, a single DNA-binding protein can bind to multiple DNA sequences. Dynabeads technology allows you to capture both rare and abundantly bound DNA. It remains one of the most cited beads for ChIP assays.

Use Invitrogen™ Dynabeads™ Streptavidin to bind biotinylated ligands such as antibodies or oligonucleotides. These “armed” beads can then be used to capture or purify any biological entity of interest. The avidin–biotin complex is the strongest known noncovalent interaction (Kd = 10–15 M) between a protein and ligand. Binding is very rapid, and once formed, is unaffected by extremes of pH, temperature, organic solvents, and other denaturing agents.
Dynabeads Streptavidin is cited in over 30,000 peer-reviewed publications for many applications, such as:
• Protein and peptide isolation
• Nucleic acid purification and next-generation sequencing (NGS) workflows
• Cell isolation
• Exosome isolation

Dynabeads Streptavidin is ideal for capture of low-abundance DNA and RNA from clinical samples (e.g., blood, feces, cerebrospinal fluid) using sequence-specific probes. The method offers several advantages, including removal of extraneous DNA, RNA, and inhibitory substances, as well as concentration of diluted and precious target into a small volume for further analysis. Dynabeads Streptavidin is commonly used in NGS where magnetic beads are utilized in several critical steps of the workflow.
Key benefits• No centrifugation, precipitation, or columns
• In-solution binding with rapid kinetics
• Excellent mechanical and chemical stability
• Reduced variability and increased consistency
• Process can be automated for isolation of biotinylated DNA, RNA, proteins, or cells

There is a wide range of surface-activated Dynabeads magnetic beads for covalent coupling of ligands to the bead surface. Depending on the bead type, the ligand can be directly linked to the bead surface or indirectly linked through a reactive intermediate. You can select beads of different sizes, with a hydrophobic or hydrophilic surface, and with a variety of surface chemistries.
For optimal results, select the right bead based on antibody or ligand type. In most applications, several Dynabeads products can be used.
Protocols can take place in a single tube, with just a few handling steps. Magnetic separation allows easy washing and concentration of target material.
